[Elecraft] OT: Coax Switch After the Tuner?

[Ron D'Eau Claire]

Your friends are probably concerned that you'll transmit into a very high
SWR if you transmit when the switch is in position to switch the analyzer
into the circuit. Transmitters do not like open or grounded antenna circuits
at the output - they're the ultimate high SWR condition. 

Of course, if you're careful it'll never happen (but never say "never", Hi)

Even so, the K3 can handle it, but it's bad practice.

A better approach would be a double pole switch that simultaneously switches
the K3 from the tuner to a dummy load and the analyzer to the tuner. Then,
should you accidentally transmit while the analyzer is in the circuit, the
K3 will see a normal RF load on its output.

Hello Wise and Powerful Reflector;

I have a couple of doublets I feed with balanced line.  The balanced  
line goes to a current balun and then a short coax run (5') to my  
tuner.  After the tuner I have another short coax run (3') to a coax  
switch that places either my antenna analyzer or the rig in the system  
so I can tune the antenna.  I've had it suggested to me that the coax  
switch places my precious K3 in danger.  The fact that this  
arrangement has worked up until this point isn't reassuring.  What say  
you all?

TIA,
